FEATURES
2-stage turbo fan
High efficiency design by 2 stage structure
Previous turbo fan
Wind
In the case of a
velocity
conventional fan, the air
outlet range was narrow
as the airflow moved to
Fast
the motor side which
meant the velocity of air
passing through the heat
exchanger was uneven.
Slow
Easy maintenance
1 Maintenance of fan motor and fan
Maintenance of the fan motor and fan can be done easily after taking off the panel as the bell mouth of the fan
can be removed easily.
A : Fan motor B : 2-stage turbo fan
C : Bell-mouth D : Panel
2 Long life filter
: standard equipment
3 Adaptation of transparent drainage parts
During installation, maintenance and operation, the drain pump and
kit can be checked easily.
Compact design
Easy installation by taking off ceiling panel of 23-5/8in. x 23-5/8in.(600mm x 600mm) size
22-7/16in. (570mm)
High lift drain pump
2-stage turbo fan
A evenly spread air distribution across
the heat exchanger is possible due
to the new 2 stage turbo fan which
produces two separate airflow
streams.
